Abstract

The invention discloses an image recognition algorithm capable of carrying out grade classification on shiitake mushrooms, which is used for solving the problems that the existing shiitake mushroom grade recognition occupies a large amount of manpower, cannot be used in a complex scene, is high in hardware cost and is not suitable for large-scale industrial production. The algorithm comprises the following steps: obtaining a front view image and a rear view image of a shiitake mushroom material; analyzing and processing the front-view image and the rear-view image through a grade recognition algorithm to obtain the quality factor of the mushroom material; Firstly, gradients of front-view and rear-view images of each mushroom material are calculated by using a Sobel operator; binarization processing is performed on gradient images of the front-view image and the rear-view image respectively; and finally, the duty ratio of the gradient image is calculated to obtain a quantized value reflecting the texture strength degree of the material image. The algorithm has the advantages of being simple in principle, high in grading precision, high in processing speed, free of complex calculation, easy to implement in an embedded system and good in industrial application value.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to an image recognition algorithm capable of classifying shiitake mushrooms. Background technique [0002] Shiitake mushrooms, also known as "flower mushrooms" and "xiang mushrooms", are fungi of the genus Lentinus agaricaceae. Lentinus edodes is an edible fungus that grows on wood. As one of the special products of our country, it enjoys the reputation of "mountain delicacy" among the people. Shiitake mushrooms are rich in various nutrients, including vitamin B group, provitamin D and mineral elements. Shiitake mushrooms have a long history of consumption in China, and Chinese medical scientists of all dynasties have discussed shiitake mushrooms. With the continuous development of modern medicine and nutrition, the medicinal value of shiitake mushrooms is also being continuously explored. For example, more than 40 kinds of enzymes rich in shiitake mushrooms can ...
